Monopulse Radar Ranging System Based On Dsp Platform

The dissertation mainly researches the range tracking and measuringtechnique of a monopulse precision tracking instrumentation radar based onone of the radars being developed inour institute. It introduces the typicalengineering specifications, composing and operating principles in details.It analyses and calculates theoretically the main technique specificationsof the ranging system based on an engineering design of a practical radar.It also simulates and analyses the tracking performance of the range loop.Moreover, the dissertation describes the operating principle of the Vernierranging technique based on phase ranging method.The dissertation summarizes the techniques of monopulse precisiontracking instrumentation radar and digital signal processing, introducingthe development of the radar range tracking and measuring technique. Then itpresents the engineering technique specifications of a typical ranging systembased on the practical engineering. It introduces the composing and operatingprinciple of the ranging system, especially details the practical methods ofspecial engineering problems such as range ambiguity resolution, blind rangeavoidance, response/reflection converting, multi stations. After this, thedissertation describes the essential principle and realization method of theVernier ranging technique. It presents a practical example of a monopulseradar's ranging system engineering design based on the DSP platform. At lastthe dissertation gives the mathmetical deductionthe formula of theⅡtyperange tracking loop equivalent noise bandwidth of the precision trackinstrumentation radar and its feature simulation curve.
